Battery pack attached to a cable

Abstract

An article comprising: (i) a handheld device including (a) a housing, (b) a powered element within the housing: (ii) a battery pack, wherein the handheld device is connected by an external cable to a functional system, wherein the battery pack is attached to the external cable, and wherein the battery pack supplies power to the powered element.

The invention claimed is: 
     
       1. An article comprising:
 i. a handheld device including:
 (a) a housing; and 
 (b) a powered element within the housing; 
 
 ii. a battery pack; and 
 iii. an external cable having:
 (a) a first segment containing battery lead wires and electrosurgical lead wires; and 
 (b) a second segment containing the electrosurgical lead wires; 
 
 wherein the handheld device is connected by the external cable to a functional system; 
 wherein the housing is connected to the battery pack by the first segment of the external cable; 
 wherein the battery pack is connected to the functional system by the second segment of the external cable; 
 wherein the battery pack supplies power to the powered element; 
 wherein the functional system includes a console which enables the handheld device; and 
 wherein the console houses a generator which supplies electrical energy to the handheld device separate from the powered element. 
 
     
     
       2. An article according to  claim 1 , wherein the powered element is a motor. 
     
     
       3. An article according to  claim 1 , wherein the handheld device is an electrosurgical medical device. 
     
     
       4. An article according to  claim 3 , wherein the electrosurgical medical device is a debrider. 
     
     
       5. An article according to  claim 3 , wherein the electrosurgical medical device has at least one electrode, and
 wherein the generator supplies power to the at least one electrode. 
 
     
     
       6. An article according to  claim 3 , wherein the electrosurgical medical device has at least one inner blade coupled to a motor; and
 wherein the motor is the powered element. 
 
     
     
       7. An article according to  claim 6  wherein the motor powers the inner blade. 
     
     
       8. An article according to  claim 1 , wherein the second segment of the external cable connects the battery pack to a plug interfacing with the generator. 
     
     
       9. An article according to  claim 8 , wherein the plug interfacing with the generator includes a monopolar three-prong plug. 
     
     
       10. An article according to  claim 9 , wherein the generator is a monopolar generator with a three-prong plug connection. 
     
     
       11. An article according to  claim 1 , wherein the battery lead wires transmit electricity to the powered element. 
     
     
       12. An a according to  claim 1 , wherein the battery pack is wired to the external cable. 
     
     
       13. An article according to  claim 1 , wherein the generator converts mechanic energy to the electrical energy. 
     
     
       14. An article according to  claim 1 , wherein the electrosurgical lead wires transmit a high frequency signal between the generator and the handheld device. 
     
     
       15. An article according to  claim 14 , wherein the high frequency signal is a radiofrequency signal. 
     
     
       16. An article according to  claim 1 , wherein the electrosurgical lead wires transmit a high frequency signal between the generator and the handheld device; and
 wherein the battery lead wires transmit electrical energy between the battery pack and the handheld device. 
 
     
     
       17. An article according to  claim 1 , wherein the generator is connected to the housing with the electrosurgical lead wires.
